Patent CA-2122521-A1 (CA)
Inventor: HART RUSSELL F
IPC: G01D18/00
Filed: 1994-04-29
Abstract: Apparatus for monitoring gaseous oxygen concentration that includes an oxygen sensor for providing an electrical sensor signal that varies as a function of oxygen concentration at the sensor. Processor circuitry compares oxygen concentration indicated by the sensor signal to at least one threshold level, and indicates when such oxygen concentration at the sensor departs from such threshold concentration level.  The apparatus is calibrated by exposing the sensor to a calibration gas having an oxygen concentration equal to the desired  threshold  concentration  level,  and storing  in the processor  circuitry  electrical  indicia  indicative  of  operating characteristics of the sensor at such threshold oxygen concentration level.  When the apparatus is thereafter employed for monitoring a gas   of   undetermined   oxygen   concentration,   the   operating characteristics of the sensor reflected by the sensor output signal are compared to the prestored indicia for determining when oxygen concentration at the sensor crosses the threshold concentration level.

Title: Output-Buffer Switch for Asynchronous Transfer Mode
Inventor: YAMADA KENJI
IPC: H04L49/111
Filed: 1994-05-19
Abstract: In an output-buffer switch for an asynchronous transfer mode, comprising a plurality of input buffer sections each for temporarily storing cells coming in through a respective input line, a time-division multiplexing section for time-division multiplexing the cells from the input buffer sections, and a plurality of output buffer sections each for temporarily storing the cells from the time-division multiplexing section which are meant for a respective output line, the output buffer sections each has a cell buffer, and a buffer occupancy ratio calculator which calculates an occupancy ratio of the cell buffer on the basis of the address information of the trailing and leading cells stored in the buffer.  When the occupancy ratio exceeds a predetermined threshold, the calculator generates a buffer occupancy state signal.  Each input buffer section has a buffer controller, an address filter, cell buffers, and a buffer selector.  On receiving a buffer occupancy state signal from any output buffer section, the buffer controller controls the address filter, cell buffers and buffer selector such that cells addressed to the output buffer section, which is about to overflow, are temporarily stored in the cell buffer other than the cell buffer used when the buffer occupancy state signal is absent.  These cells are fed out from the buffer when the occupancy ratio decreases to below the threshold.  As a result, when any one of the output buffer sections overflows, it is recovered immediately without cells being discarded.
